Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
Hello there!
Well, that sentence is easy to memorize because it is short. Compare to what I have to memorize :)
How can I remember the definition?
Well, personally, I used different strategies to study Biology.
The first one "Flashcards".
Not every students like flashcards, but I do. In front of the card, you write "Gene". Then at the back of the card, you write the definition of it.
You keep reading it for like 3 times then you'll remember it.
Another strategy I used it writing it down. And this comes after you finished with the flashcards.
Take a piece of paper and write the definition down without looking at the flashcard. Write it down several times.
The next strategy is to test yourself. Leave it for like 4 minutes and go do something else. (Personally, I usually listen to music).
Then after 4 or 5 minutes, come back to it. Without looking at the flashcards or the paper, try to repeat the definition in your mind. Then repeat it out loud. Then write it down again to see if you remember the correct grammars. For example, you might don't remember how to spell "Chromosome".
That should be enough! :)
I used these tips to study Anatomy and some other science stuff. It works for me. I hope it works for you too.
As always, it is my pleasure to help student like you!
Answer:
it's the last one, everything else would be an increase in the population
